- Composite clinical rank order on iden- tity diffusion vs identity integrity, measuring continuity vs discontinuity of past, present and future; integra- tion vs lack of integration in inter- personal and work relationships; inte- gration vs lack of integration of the total personality; and effectiveness vs ineffectiviness in self-definition and achievement of ends. The criteria were largely based on Erikson's discussion of identity.
